MEANS FOR TRANSMITTING POWER.

SPECIFICATION forming part of Letters Patent No. 477,469, dated J une21, 1892.

Application led August 20, 1891.

To all whom it may concern:

Be it known that we, CHARLES T. TARPEN- NING, residing at Fresno, in thecounty of Fresno, and LINCOLN B. SHERWooD, residing at Turlock, in thecounty of Stanislaus, State of California, citizens of the UnitedStates, have invented certain new and useful Improvements in Means forTransmitting Power, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in meansfo'r transmitting power, designed for use in anyand all connectionswhere it is desired to transform rectilinear :into vertical motion. Itis designed, primarily, for windmills; but the invention is notrestricted to such use.

It has for its objects, among others, to provide improved, simple,cheap, vand durable mechanism for transmitting the power and for takingup orpreventing wear upon the crankshaft. Vc provide 'the lift-arm withan elongated loop at the end farthest from its fulcrum, and in this loopthe crank-shaft is dcsigned to work. This crank-shaft is provided with acollar which turns back and forth as the wheel turns, which tends toreduce the friction. One-half of the loop is formed on the lift-arm, andthe complement is formed by a detachable piece secured thereto toprovide for ready insertion or removal of the crank-shaft therefrom. r

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure l isaperspective view ofouriuvention. Fig. 2 is a longitudinal vertical section through thesame.

Like letters of reference indicatc'like parts in both views where theyoccur.

Referring now to the details of the drawings by letter, A designates asuitable framework or support, which may be of any wellknownconstruction, and upon which aresuit- Serial No. 40 3,220. (No model.)

ably supported the boxes or bearings a for the crank-shaft B. Vile havenot shown more l of the frame-Work or support or the tower or wheel, asthese parts do not form a part of the present invention. The hub portionO ofl the wheel is shown; but it will of course be understood that thewheel and its hub may be of any of the well-known or preferred forms ofconstruction. The means for throwing the wheel linto and out of the windand for stopping the same may be of any preferred form.

D is the lift-arm, pivoted at one end between ears or lugs b on theframe-work or platform or support, as shown. At a point substantiallymidway its ends itis formed with an enlargement c, to which is swiveledor otherwise connected the bifurcated head E, which is adapted toreceive the plunger or pump rod, (indicated by dotted lines at d.) Theunder side of the lift-arm at this enlargement is formed with an offsetor shoulder e and from that point toward its other end with a halfloopf, as seen best in Fig. 2, the remaining portion of the loop gbeingformed by the halfloop h, which at the ends is provided with fiatbearings i' to engage' corresponding bearings j upon the upper half ofthe loop, and to which they are detachably secured in any suitablemanner, as by the bolts Z, as shown in Fig. 2. Upon the crank-shaft atthe point within the loop is a collar F of any suitable material, andwhich turns back and forth as the wheel revolves and serves to lessenthe friction and prevent wear on the crank-shaft.

The operation will be readily understood from theforegoingdescriptiomwhen taken in connection with the annexed drawings,and a detailed description thereof is not deemed necessary. Forinstance, We may employ a packing between the upper and lower parts ofthe loop, as indicated at e" in Fig. 2, so that should the parts becomeworn a part of the packing can be removed and the loop still lit tight,thus taking up the lost motion and wear.

What we claim as new is-A 1. The combination, with the bifurcated headand the lift-arm pivoted between the bifurcations of said head andformed with enlargement, offset, and half-loop with flatbearing-surfaces, of the half-loop having flatbear- IOO ing-surfaces andadjustably connected to the hat' bearings of the portion of the loopupon the arm, as set forth.

2. The combination, with the pivoted liftztrm having enlargement andshoulder or offset at said enlargement lncl an integral onehalf loop, ofthe complement of the loop having a portion engaging said shoulder and iwith fiat bearings, and detachable means connecting the parts at saidbearings, and the bifurcatetl head, between the bifurcations of whichsaid lift-rod is pivoted, and the crankshaft having the collar bearingupon and Working in the said loop, substantially as described.

In testimony whereof We affix our signatures in presence of two Witnesses.
